**Circles ncert solutions Chapter 10 Exercise 10.2 Question 2**

**2. If, TP and TQ are the two tangents to a circle with centre O so that then is equal to:**

**(A) (B) (C) (D) **

**Solution:**

We know that tangent is always perpendicular to the radius of circle. Therefore, and are both because TP and TQ are tangents to the circle and OP and OQ are radii. **(1)**

**In Quadrilateral TPOQ**

(Sum of interior angles of Quadrilateral is equal to )

**Therefore, answer is (B)**
